Electric gear pump 4 CZ

Electric pumps of the 4 CZ range are used to pump and supply oil in machine tools, esp. for pressure lubrication of bearings.

Viscosity of the pumped liquid must not exceed 115 mm2.s-1, temperature 0-60°C, and the size of impurities 0.1 mm.

Pumps must not be used for pumping flammable liquids. Electric gear pumps of the 4CZ range feature a special flanged shape adapted for installation directly onto the oil tank. The suction pipe has to be located in the tank to prevent the pump from sucking in contaminated oil. The opening of the pipe for overflow of redundant oil has to be designed in order to prevent the excessive breaking of oil.
